Is this ecu a decent one or one of the newer junk ones

If it was made in the last 25 years, no.

I’d carry a spare in my trunk.

I have old chrome box that always ran great, potting is coming out though can I repot this if so what should I use?

Best way to find out is run it and see!
As said, carry a spare just in case so you won't get stranded (that goes for pretty much any stock-type ecu, even the "good" ones..) but it's likely fine.
I had one like that from the "MP electronic ignition conversion kit" that was popular in the early 2000s and it worked flawlessly.
